control arm and bushing problems appear on braking. alignment is only covered for the 1st 1200miles after that it's on you. even if they did, they will blame your aftermarket wheels. check if any counterbalance weights fell off your rims as a first step. but since you have tire wear issues, you should get an alignment. since you have only a few miles left on your warranty, get an inspection of the car from the dealership for everything. you would probably have to pay for the inspection out of your own pocket, about 1/2 to 1 hr tech time but it was well worth it and saved me more than 1kcad for what was found.
